My mom remembers making Moshey Pie when her grandmother was making other pies and using the leftover dough. We had some left from a pie - so we decided to make one.
Basically all you do is roll out the leftover dough and press it into a tart pan (if you have enough or just lay it flat like we did.)
Cover the dough with brown sugar and dot with butter. Than dribble the top with molasses and cook until the dough is done.
Easy peasy. Lucille could almost do it by herself.
